16:30 < |cos|> I'm a long time feh user who recently discovered captions
16:31 < |cos|> unfortunately captions are practically useless for me since they only handle ascii :/
16:31 < |cos|> before anyone says "patches are welcome"
16:32 < |cos|> do you know if anyone has ever tried to add functionality for non-ascii in captions?
16:32 < derf0> Nope, I don't think anyone ever tried.
16:33 < |cos|> then i'll make a half-hearted attempt (:
16:33 < derf0> But it shouldn't be too hard. Right now, feh ignores non-ascii input in caption mode. And I don't even know why, probably because there might be weird problems otherwise.
16:34 < |cos|> feh displays non-ascii characters in the filename correctly, it seems
16:34 < derf0> Yeah.
16:35 < |cos|> and if i mess with file->caption directly in the source it kind of works
16:36 < derf0> Hm, removing the isascii(keysym) in keyevents.c breaks more than it helps.
16:38 < |cos|> i guess giblib's only documentation is it's source code?
16:39 < derf0> Yeah, unfortunately.
16:39 < |cos|> just to get me started at the right end. is it wrapping imlib1 or imlib2?
16:40 < penma> imlib2
16:41 < |cos|> thanks
19:11 < |cos|> ...and i'm giving up
19:11 < |cos|> handling multibyte characters with low level X11 libraries can of course be done, but not easily
19:12 < |cos|> i guess there is a reason why libraries like GDK and such exist
19:12 < derf0> Yeah.
19:13 < derf0> Well, I'm afraid you'll have to live with feh not supporting non-ascii tags for now.  At least I'd like not to add further dependencies ;)
19:14 < derf0> Unless of course someone comes up with a different method. Or something. We'll see.
19:14 < |cos|> i'll live with it (:
19:16 < |cos|> it's still the best alternative -- by far
19:17 < derf0> Glad to hear :)
19:19 < |cos|> thanks for creating/maintaining it!
20:32 < |cos|> for what it's worth, this patch kind of hacks multibyte support into feh captions http://pastebin.com/7DxcYX2B
20:32 < |cos|> it's ugly as hell, buggy and no way near complete
20:35 < |cos|> i'll probably good enough for me to use personally, but a proper implementation should of course enable normal backspacing et cetera
20:35 < |cos|> (and place the im and ic creation calls somewhere more appropriate)
20:36 < |cos|> i'm afraid i don't reckon i will put in the work to implement it cleanly :/
20:37 < derf0> Well, your patch is a perfectly fine starting point, so thanks a lot already :)
20:37  * derf0 has saved it and may use it later on. But not today.
